You just need to modify your existing light flow a little and add the contact sensor as a condition.
The light should only go out when the shower door is open and no movement is detected.
I don’t know your light flow, but here are two standard examples:
If you post a screenshot of your light flow, then it’s easier to show you what changes need to be made.
If you use a timer app instead of the build-in delay flow cards , you can also restart it as soon as the shower door is opened so that the light doesn’t turn off because the MS has not yet detected any new movement.
I don’t recommend to use the build-in delay flow cards. Once this card has been activated, the time runs to the end, no matter what happens. This time cannot be interrupted or restarted. I recommend a separate timer app for such use cases, e.g. the Chronograph app.
I recommend the following tutorial as a basis for a light flow with a timer:
[Simple] Lights turning on/off based on motion
Although the tutorial was created with Standard Flows, it can also be created with Advanced Flow without any problems.
